CVE-2024-7629: CWE-80 Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) in marla14 Responsive Video
The Responsive video plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's video settings function in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires responsive videos to be enabled for posts.
AI Analysis
Technical Summary
The Responsive Video plugin for WordPress (marla14) suffers from a stored XSS vulnerability (CWE-80) due to improper neutralization of script-related HTML tags in user-supplied attributes within the video settings function. Authenticated users with contributor-level privileges or higher can inject arbitrary JavaScript that executes in the context of any user viewing the affected pages, assuming responsive videos are enabled. This vulnerability affects all versions up to 1.0. The CVSS 3.1 score is 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, and partial impact on confidentiality and integrity. No patch or vendor advisory is currently available.
Potential Impact
An attacker with contributor-level or higher access can inject persistent malicious scripts into pages with responsive videos enabled, leading to potential theft of user credentials, session hijacking, or other script-based attacks against users viewing the infected pages. The vulnerability does not affect system availability. The scope is changed (S:C) because the vulnerability affects resources beyond the attacker’s privileges. Confidentiality and integrity impacts are low, as indicated by the CVSS vector. No known exploits have been reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access to trusted users only and consider disabling responsive video functionality if possible. Monitor official plugin sources for updates or patches addressing this vulnerability.
